To all whom imag concern:

Be it known that I, JAMES BREN'roN, a citizen of the United States, anda resident of Waukegan, county of Lake, and State of Illinois, haveinvented certain new and useful Improvements in. Quick-Opening Faucets,of which the following is a full, clear, and exact description. y v

The invention relates to faucets or cocks of the quick opening type andwhich are usually providedy with multiple screw threads of sharp pitchso that thevvalve can be opened and closed by turning the valveoperating stem through a partial rotation.

5 The valve of such a quick opening faucet or cock is arranged on thedischarge side of the valve seat and is apt te be opened accidentally bythe pressure of the water supply and particularly after the operatingparts become loosened or worn.

The present invention seeks to provide improved means for frictionallyholding the valve against accidental opening and consists inthe-features of improvements hereinafter set forth, illustrated in thepreferred tially in vertical section, of the improved faucet or cock.Fig. 2 is a section on the line 2 2 of Fig. 1.

The faucet or cock comprises a suitable casing 1 having a partition 2provided with The partition is provided on its upper or discharge sidewith a raised valve seat 4 about the port 3. Preferably also, an annularrecess 5 is provided in the upper face of the partition extending aboutthe valve seat. Above and in line with the port, f

the casing is provided with an upwardly extending cylindrical portion 6.

A valve 7 is arranged on the discharge side of the valve seat and itslower end is arranged to extend within the recess 5 of the partition 2.Preferably, as shown, the lower end of the valve is provided with awasher 8 which is held in place by a screw 9 and which is arranged toengage the valve seat 1.

In the preferred form shown, the enlarged upper end of the valve isprovided with external screw threads 10 which cooperate with internalthreads 11 formed upon the upwardly extending portion 6 of the casing.

These threads are multiple (quadruple in the form shownland are of sharppitch so that'the valve can be opened and closed by turning it through apartial rotation.

In the preferred construction set forth the valve stem 12 is separa-tedfrom the valve and is provided with a square lower end portion 13 which.fits within the correspondingly shaped socket or bore 14 in the upperenlargedv portion of the valve. Preferably also, the valve stem is heldagainst vertical movement and for this purpose is provided with anintegral collar 15 and a cap-nut 16 cooperates with the collar toprevent the ver- Ytical movement of the valve stem. As shown,

the cap-nut 16 is threaded upon the upper end of the extension 6 and abody of packing material 17 within the cap-nut extends overthe upperedge of the extension 6 and against the valve stem to form tight jointstherewith. The collar and the upper portion of the cap-nut arepreferably conical in form as shown.

Means are provided for fri'ctionally holding the valve stem in any. setposition to thereby prevent any accidental movement or opening of thevalve. For this purpose a series of washers are mounted upon the valvestem, one of the washers being connected to rotate with the stem, andthe other washer or washers being heldin iixed position and infrictional Contact with'the rotatable washer. Preferably, as shown,three fiat metal washers 18, 19 and 20 are mounted upon the squaredportion of the valve stem immediately below the collar 15 and thesewashers are arranged within an internal recess or seat in the upper endof the cylinder extension G. The intermediate washer 19 is provided witha square opening which loosely lits the squared portionof the valve stemso that this washer rotates with the stem. The other washers 1S and 20are provided with round central openings and are clamped in fixedposition between the packing 17 in the cap-nut 16 and the upper end ofthe extension 6. In this way the fixed washers 18 and 20 bear withsufficient friction upon the washer' 19 to prevent the accidentalrotation of the valve stem 18 and the accidental movement of the' valve.

The collar 15 of the valve operating stem is clamped between the upperwasher and the packing 17 within the cap-nut 16 so that the valve stemis held against vertical movement, but the rotation of the valve stem,of

ChA

"withthe shoulder at the upper end ofthe screw thread in the extensionwill holdjit 19 which rotatesV with the valve stem fits theVsame'somewhat loosely so that it can be gripped with considerablefriction between the fixed washers 18 and Q0 without causing v unduebinding between the rotatable valve Y stemand the fixed parts of thefaucet. The

arrangement prevents undue wear between Y the movable and fixed parts. iThe lower end of the valve steam also fits rather loosely within thebore of the valve so that the latter is self-'adjusting upon its seatandV so that there will be no undue binding'l between the screw threadsof thevalve and of the casing'. The valve stem is provided at its upperend with a suitable handle 21 heldin place by a screw 22.

It is obvious that numerous changes may be made in the detailsofstructure without departure fromthe essentials of the invention asdefined in the claims. I claim as my invention 1; `AV faucet of thequick opening type hav- Y ing a rotatable valve-operating stem. a washerloosely mounted on saidrstem but connected to rotate therewith, andmeans held against rotation on saidfaucet for frictionally engagingsaidvwasher.

2. A faucet comprising a casing having a valve seat,a valve on thedischarge side of said seat having quick acting threads, a rotatablekstem for operating saidl valve, a washer Vloosely mounted on said stembut connected to rotate therewith, a cap-nut for said casing, andmeansheld against rotation between said cap-nut and casing forfrictionally engaging said washer.

3. A faucet comprising a casing having a valve seat, a valve on thedischarge side of said seat having quick acting threads, a rotatablestem for operating said valve having a collar thereon, and a washerloosely mounted on said stem but connected to rotate there-` with, saidcasing having mea-ns cooperating with said collar to hold said stemagainst vertical movement and for frictionally en-V gaging said washer.
